Such clinching application of'the sides a: of the band may be accomplished by suitable die members 25 and 26.

The die members shown are similar and annular and each has a sha )ing channel 27 for deflecting the ends a: an securely applfying them around the peripheral parts 24 o the head disks. dVhen the die members are brought together the surfaces of the channels 27 cause the proper deflection and bending of the band sides w; and, as shown in Figure 4, these sides are deflected into intimate engagement with the periphery parts 24 so that these parts 24 will be encompassed and securely clenched and clamped by the deflected tire sides. The ends of the tire sides are then within the recesses 23 and not only will the tires then securely clamp the head disks together at their peripheries but the tire will,

' also lock itself securely to the head. Prefer- LabIy the application is such that the side faces of the applied tires will be flush with the side faces of the heads so that the reels can be accurately stacked and so that the tires will not interfere with the winding on or unwinding from the reels of wires or other material.

The annular ridge 22 in the tire provides the outer groove 21 for receiving a belt by which the reel is to be turned or braked, and

such ridge also forms a seat or base betweenv which and the deflected sides of the tire the head disk peripheral parts 24 are intimately received and clamped.

It will be noted that the semi-circular sides of the applied tire structure and the projections of the ends thereof a considerable distance within the outer faces of the head-produces a very strong reinforcing and clamping structure which is very resistant to blows 0r bumps, the direction of. blows or bumps being through the radius center of the semicircular sides of the tire so that bumps or billows, instead of tending to spread and loosen the tire structure, will tend only to force its sides more intimately against and around the head peripheral parts 24.

Having described my invention, I claim as follows:

1. A spool or reel comprising a barrel and head structures secured thereto, each head structure comprising two similar disks, each disk having its inner edge recessed and said recesses joining to form an annular groove, each disk on its outer side having an annular recess a short distance radially inwardly from said groove, the peripheral section of each disk between said groove and the corresponding recess being of substantially semi-circular cross section, and a sheet metal tire deflected into said dgroove and having its sides deflected aroun said semi-circular sections with their ends extending into said .recesses whereby said tire clamps said disks together and clinches itself thereto.

2. A spool or reel comprising a barrel and head structure secured thereto, each head structure comprisin two disks of non-metallic-material, the adjacent peripheral edges of said disks being cut away to leave an annular peripheral groove, each' disk in its outer side having an annular recess a short distance inwardly from said groove the pe= ripheral section of each jdisk between said groove and the recess being rounded to resent a surface of arc'uate curvature, a s eet metal tire deflected intermediate its sides to fit in said groove and having'its sides deflect ed intimately against and around said arouate surfaces with the ends thereof extending into said recesses, the outer surfaces at the sides of said tire being flush with the outer sides of said disk a v 3. In a spool or reel of the class described, a head structure comprising cylindrical halves of non-metallic material, each half having its inner edge recessed and said recesses joining to form an annular groove, each half at its outer side having an annular recess a short distance radially inwardly from said groove, the peripheral section of each half between said groove and the corresponding recess being of substantially semicircular cross-section, and a sheet metal tire deflected into said roove and having its sides deflected around said semi-circular sections with their ends extending into said recesses whereb said tire clamps said halves together and 0 inches itself thereto;

n testimony whereof I have hereunto subscribed my name at Chicago, Cook County,

Illinois.
